# TODO Is /opt always a good destination?
# It is good to always have one location to avoid downloading again
# It is bad to have a location hard-coded because we don't know if it
# will always exist and have space... better to use mktemp, but then
# have to ensure that desired version is already installde with 
# dpkg-query -W elasticsearch and parse the output...
